ABSTRACT:
A surface active compound comprises at least one lipophilic group and at least one hydrophilic oxyethylated group linked together through acetal linkages so that, on acidification of an aqueous medium containing such a surface active compound, rupture of such acetal linkages permits separation of said lipophilic group, possibly with lipid material associated therewith, from the aqueous medium in which the oxyethylated groups remain so in turn permitting recovery of such lipophilic groups and any such lipid material, and effective elimination of active surface active compound from the aqueous phase.
